My 4th (or 5th) build and OC

post #1 of 4
Thread Starter 
My first post...my first build was way back in '92 and it used a Cyrix CPU, a 486 with a whopping 12 MEGAbytes of RAM. I have a question later and hope you guys will let me digress a bit first.

I wanted to tell about my current (and first) OC success that I did using durch's awesome thread on how to do it right. I built this machine about 6 years ago and it was top notch then, but it needed some tweaking to get it up to running a program I dearly love; Empire Total War.

It's AMD of course, I've only built one Intel machine and that one was from parts I had for my mother to use as an E-machine, (the MOBO/CPU bundle was very cost effective). This machine has a Gigabyte M59SLI-S5 MOBO, Athlon 64 X2 5000+ processor, 2 - 1G chips of Aeneon DDR2-800 memory, 2 - 120 GB SATA2 drives that I have striped (RAID 0) and 2 - Nvidia 7950GT in SLI. I had 2 old chips of Corsair DDR (1) memory that had heat spreaders on them and took them off to put on the Aeneons, nice fit with real 10% silver paste, and the cooling solution for the NB, SB, and MOSFETs were likewise repaired with real thermal paste and cool very well. The other parts that need cooling are likewise well done, Zalman CPU, good air flow, sadly though silent solutions for the GPUs. They're next.

Using durch's steps, I was able to find the MOBO max bus speed to be 380mhz, and the CPUs max frequency to be 3109mhz. The memory turned out to be the problem child, as I'm guessing most of you guys know. Long story short, I wound up with these final values, Bus speed 310, CPU multiplier x10, HT multiplier x3 (SB>NB and NB>SB are at x5) CPU voltage 1.45v, and my red haired younger brother DDR2-800 memory running in 533 mode with 5-5-5-18-26-2t timings and a +0.1 volt increase on them and all the MOBO chips. This setup had yielded a 30,000+ 3DMark03 score. The CPU is running at 3092mhz (almost a 19% increase) and the RAM is running at 386.5mhz (one channel) as measured by CPU-Z. This is the highest memory frequency I can get and have CPU frequency be at or above 3000mhz. It's hot here in Fla and the ambient air is 80 degrees (A/C is on the fritz) but the CPU hasn't gotten over 55 degrees celsius during any of the ORTHOS stress tests, probably because of the huge Zalman cooler. I'll be running a 24 hour blended test when I finish this post.

My question is this, is it better to be running this OC setup than, say 2800mhz CPU speed and 350mhz memory speed with DDR2 set at 800?

Might want to move the memory slots to the properly colour coded channels for dual channel operation, resulting in better all-around performance. At 386.5Mhz (773Mhz DDR) you are running slower than 800Mhz. However at 350Mhz (700Mhz DDR) and 2800Mhz CPU speed, you would still be running even slower. Your current OC is probably the best possible.

Thanks for your input. I have the two in the recommended 1 and 2 sockets. My stress tests failed that configuration though and I got to thinking when looking at that bios startup saying "DDR2 533 single channel 64 bit" versus "DDR2 800 dual channel 128 bit": What if I'm stressing too much on the processor spd and not giving a good enough look at memory. So after some more play this is what I've come up with...

Bus spd 228; CPU multiplier x13, HT multiplier x4, CPU voltage 1.4, DDR2 800 with default timings (5-5-5-18-26-2t) and the memory voltage + 0.1 to 1.9v. This has yielded a 3DMark03 score of 29,870 and gives me a CPU and memory frequencies of 2974 and 425 respectively, almost 14% increases in both. HT link dropped to 915 from stock (1k) but durch says it won't be missed. I guess the 3DMark score proves it.

The processor is running 5 degrees cooler too. This configuration has withstood 7 minutes of both large and small ORTHOS tests. I'm about to find out if it can withstand 2 or 3 hrs of the blend right now.

Glad to be on board. This is a good forum. Been a long time since I posted on any forum, hard finding words that don't link to advertisments these days. BTW, did you remove the duplicate post in the other category? Sorry I didn't read the rules. Then again, this is an overclocker's forum and I suppose you get a lot of those types here.

Just FYI...

Orthos blended test ran 11 hours last night so I'm keeping this configuration. Forgot to mention but maybe some of you might be interested. This machine is running on a 500 watt power supply, very little margin for error since I figure to be using 450 watts at least, so keeping voltages down was almost a first priority. Since this configuration has only two things increased by 0.1 volt, processor and memory, I'm very happy with the results. Kudos to durch and the whole team here.

You will definitely hear from me when the bulldozers get to Zambezi.
